You can start from any of the options mentioned above however make sure to follow the rule of BODMMAS but you can start from (D) 54÷3 if you just really want a section to start with
Let width be x
Length would be x + 3
Area = L * W
Make an equation
(x) * (x+3) = 70
x^2 + 3x = 70
x^2 + 3x - 70 = 0
Quadratic formula
(-3 +/- rt 3^2 - 4 * 1 * (-70))/(2 * 1)
x1 = (-3 + 17)/2, x2 = (-3-17)/2
x = 7, x = -10
Dimension cannot be negative
Solution: width = 7
Length = 10
$34.80
$58.00 x (1-0.4) = $58.00 x 0.6 = $38.40

Answer:
Step-by-step explanation:
<u>As per steps given the congruent pairs are:</u>
- AB and AC
- BD and CD
- Angle B and angle C
So two sides and included angle - it represents side-angle-side or SAS congruency theorem
